If you are under 28 and can get a "holiday visa" where you just go to a country and work, it is easy to go to most countries. However, I'm older and I've found getting a work visa impossible. Really, its such a nightmare I can't do it myself at the moment. I also feel I can't leave my house or job here because I won't be able to pay my mortgage. However, I have done it in 2008, so I'd recommend other guys to get their life to a stage they can go - but it's not easy.

"Woman is a violent and uncontrolled animal... If you allow them to achieve complete equality with men, do you think they will be easier to live with? Not at all. Once they have achieved equality, they will be your masters." Cato the Elder

If you get an account, I think you can filter usa.jobs so that it yields only the websites of the companies hiring for International jobs.

On a lot of boards, you click on a job, which takes you to another board where you have to put in another password, and the job may be expired. I haven't used a job board that does that in years, but in the past, you could follow a wild goose chase of job boards and spend your time filling in password forms to create accounts online.
